So, 440 block that was in question has been dropped off at a new machine shop this morning. Guy is going to inspect it for me, for free and give me one last opinion before I decide what to do with it. To refresh memories, original machine shop failed to deck it, line hone it, didn't hot tank it. They did bore and hone it and improperly install the cam bearings. I've taken it to 2 other shops since and have gotten split decisions, one saying the block is trash and the other saying the bores and hone job are fine and within specs and that they could finish the job. So we shall see today.
